LED signal wiring/automated block control

Tomar Industries LED signals

I picked up some tri color Led signals and have some wireing issues. These have a green,white and a bare copper wire. Im hooking the signals up to a logic rail block control system(BA1) to operate the lights.

problem 1)The tomar instructions say that the white wire is the ground, green and red are positive and need resistors . there is no red wire just a copper?

Problem 2)the Logic rail BA1 says that I only need to put 1 resistor on the common path(ground?)I tried this and I get an over load on my transformer?

What did I miss?

Tomar requires Different resistors based upon the color and they are significantly different. Can't remember the actual values, but that is what the problem is. I haven't done one in awhile, but you can't just put one on the common.

It may appear that the red sheathing got pulled off of the wire that is just bare copper. Would probably insulate the copper wire or bring it back to you LHS for replacement.

thanks Bob

I bought 3 of the tomar signals and all 3 have the bare copper wire? I should call tomar and ask them directly..

Tomar Signals

If your transformer is shutting down then the bare copper wire is touching the signal's metal mast or other led post.
First look to see where it's shorting out. Then cover the bare wire and use it with the white lead. If signal displays red that's the red wire. Your transformer should put out 18 volts. Most calculations to bring down the voltage to about 1.8 volts for leds are based on 12 volts so think about this when you hook up your signals. You don't want to burn them out. I have all most all Tomar signals and use a Radio Shack 12 volt transformer to lite them. I put a resistor on all the colors so I can better adjust their brightness or you can put just one on the white.

I just got done with wireing....

The copper wire was considered the "red" wire, I called tomar this afternoon and thats what they told me. The bare copper and green is a + wire and the white was the ground per there instructions. I have never seen a bare wire like this before???

anyways Its set up and works like it should. I just need to calabrate the photo cells to the lightness in the room. It works pretty cool and I love the dim LED lights as it looks to scale
